PRE-SAFE®
(preventative occupant
protection)GWARNING
The PRE-SAFE ®
system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions.
PRE-SAFE ®
takes preemptive measures to
protect occupants in certain hazardous
situations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or, in vehicles with DISTRONIC
PLUS, BAS PLUS intervenes powerfully
R in critical driving situations, e.g. when
physical limits are exceed and the vehicle
understeers or oversteers severely
PRE-SAFE ®
takes the following measures
depending on the hazardous situation
detected:
R it adjusts the front-passenger seat if it is in
an unfavorable position.
R the air pressure in the side bolsters of the
seat cushion and seat backrest of the front
active multicontour seats is increased.
R if the vehicle skids, the side windows and
sliding sunroof are closed so that only a
small gap remains.
If the sliding sunroof or a side window is
obstructed during closing, the closing
procedure is stopped. The obstructed sliding
sunroof or side window opens again slightly.
If the hazardous situation passes without
resulting in an accident, all settings made by
PRE-SAFE ®
can be reversed. The air pressure
in the side bolsters on the active multicontour
seat is reduced again.
If the seat belts are not released:XMove the backrest back slightly, but only
when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released.GWARNING
Make sure that nobody can become trapped
as you adjust the seat.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
Seat belts
Important safety notes
The use of seat belts and infant and child
restraint systems is required by law in all 50
states, the District of Columbia, the U.S.
territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened when the vehicle is in motion.
i For further information on infants and
children traveling in the vehicle and on
infant and child restraint systems, see
"Children in the vehicle" ( Y page 55).
GWARNING
Always fasten your seat belt before driving off.
Always make sure all of your passengers are
properly restrained. You and your passengers
should always wear seat belts.
Failure to wear and properly fasten and
position your seat belt greatly increases your
risk of injuries and their likely severity in an
accident.
If you are ever in an accident, your injuries can
be considerably more severe without your
seat belt properly buckled. Without your seat
belt buckled, you are much more likely to hit
the interior of the vehicle or be ejected from
it. You can be seriously injured or killed.
